Before you write your characteristics here, try to write the gmod_mcore_test 1 and mat_queue_mode -1 commands in the console, which will help raise the FPS. Already tested? Then read on.

If you have few FPS on the map, then please write here the characteristics of your computer. Based on these characteristics, I will analyze and try to make more improved optimization in future version of the map. And also write how many FPS you have inside the vagons.
